Instructions:
Cut the back pockets out of old jeans (make sure the pockets do not have holes). Then trace the shape of the pocket onto cardboard or photo matting (you can buy scraps of this at craft stores).

Cut out the cardboard shape using scissors or a razor knife. Hot glue the cardboard to the back of the pocket. The last step is to attach magnetic tape to the cardboard and you have a magnetic pocket. These are great for the refrigerator to hold pens, coupons, bottle opener, etc.
